Fried eggs on potato chips with vinegar

Fill a bowl with potato chips so the eggs can slide straight on top when done.

Melt butter in a non-stick pan.

Crack in the eggs, keeping the yolks whole (cracking into a bowl first is safer); season with a little salt and pepper.

Add a little rice vinegar to the pan.

Cook gently, uncovered so the yolks stay yellow, until the whites are solid and the yolks runny; pull any egg that is done to the edge or off the heat.

Slide the eggs out onto the chips.

Variation: fry the egg in chili crunch instead of butter, spoon more chili crunch oil on top, and finish with a generous amount of green onion.
